Interesting Post on CloudyNights #ExploreScientific #CloudyNights

I ran across this post on CloudyNights about the standard discussion about "How can I get into Astrophotography for < $1500? "  
I thought I would share the link to it so that if you are interested, you could share your experience with the iEXOS 100 and EXOS 2 PMC-Eight mounts. 
It seems that our mounts always get left out of the conversation, and I am trying to get the word out if possible.

Thanks everyone! I very much appreciate it!

Hi Pantelis 

You have captured some good images for the short amount of time you have been doing this.
Well done.
One initial comment is that perhaps you should loose the st4 cable and use pulse guiding directly to the ascom driver via a poth hub instead.
Most don't use this cable any more as more accurate results can be achieved using pulse guiding

There will be plenty of posts about this on here so have a search.

Cheers
Dave

HI Wade,'

No problem... The DEC offset rate setting would be set in the ASCOM driver and would be user controllable to set a constant rate offset to guide against. If you look in the MISC tab on the ASCOM driver you will find the setting for the RA axis.

Jerry,

I just went backed and watched today's earlier stream where you talked about my guiding issue. I will try all of the tips you and others here on the forum have given. The part about a rate off-set setting for correcting DEC and RA mount float, could that be an added feature that we, the user, could control ourselves through the PMC8 configuration manager? I'd really like to have that as an option, and to have full control over it.

Also, thanks so much for the level of support you give here. I own a fairly expensive mount from another company and I can barely get them to respond to an email. This is extremely refreshing for a customer.

Thanks again,

Wade Prunty

For Those Having Problems with ASCOM Clients Running On ASCOM Platform 6.5 #ExploreScientific #ASCOM

Jerry Hubbell - Explore Scientific VP Engineering
 

If you have upgraded your ASCOM Platform to version 6.5 and have subsequently had problems with an ASCOM Client program such as SGP or other, please read this thread on the ASCOMTalk Groups,io forum. I think it is open to the public to read so you do not have to join the group (I don't think), but you may want to join anyway.

https://ascomtalk.groups.io/g/Help/topic/problems_connecting_my/75883422?p=,,,20,0,0,0::recentpostdate%2Fsticky,,,20,2,0,75883422

There is some good information on how to turn on the ASCOM Tracing (log file) to further understand what might be happening with your client program. I would suggest that anything you may find out when using this tool should be forwarded to Peter Simpson, one of the developers of the platform. Peter is very easy to work with and welcomes any questions.

Re: Polar finder scope query from a total beginner #polaralignment #iEXOS-100

brian skinner
 

Hi Adam, your set up is the same as mine. I have just, I think, mastered the Polar Scope, here is my modus operandi;

1. Remove camera to help ease of viewing through the PS

2. Make sure your mount is and stays level

3. You must Collimate the PS, its tricky and patience is required for sure, but if I managed it....

4. Adjust the mount so that it is pointing roughly towards Polaris/North

5. Using the latitude adjuster, adjust the PS such that that its reticle is at or around the same latitude as either Ursa Major OR Cass, depending on which is most visible/ convenient.

6. By eye, rotate the PS reticle in its mounting bracket until the constellation of your choice angularly aligns with the actual constellation. This takes a little time but obviously this needs to be as accurate as possible, again, if I can do it....

7. When 6 is achieved move the mount physically and gently, until you see Polaris in the PS.

8. Using the latitude adjuster and physically left to right mount adjustment, place Polaris in the little gap in the PS Polaris line. When that is achieved you have a good Polar Alignment, I am managing 3 minute exposures without major trailing.

9. Power up the mount, set up the WIFI and you are good to proceed to alignment.

Regarding finding your alignment stars you first need to ensure your camera is focused well, and certainly I would also recommend a red dot finder, I have one which fits the camera hot shew bracket. Don't forget, the longer your focal length, the narrower the field of view so, it is possible your alignment stars will be outside your live view image, a red dot finder will allow you to home in gently using the ES App UDLR buttons.

Hope this helps you, kind regards, Brian

Hi Bob,

I don't recall anything specific, but I may have mentioned that I want to tweak the ASCOM driver to try and further improve the accuracy of the slews further. This is related to my calculation of the time it takes to actually do the slew so that the term I use to calculate the Slew Target RA value is better. Currently the final position is good to around 3 or 4 seconds in RA (45 to 60 arc-seconds). I would like to get this to within 1 second of RA (15 arc-seconds). I have that on my todo list of things to tackle.

Re: Astrophotography Done with the iEXOS-100, EXOS 2, and G11 Post your Pictures and Details! Lets Show What These Mounts Can Do. #G11 #astrophotography #iEXOS-100 #EXOS2

p.bampoulis@...
 

Hello,

I am new to the forums and very new to astrophotography. Last month I got my first eq mount, the iexos 100 and so far I am very pleased with its performance. I am using it with the skywatcher evostar 72 ed, and a modified canon eos 1000d. I manage to PA with sharp cap (50 mm TS guidescope + ZWO ASI 120 MC-S). Two days ago I was also able for the first time to set phd2 and guide, using the ST4 cable. 

I image from my backyard in Cologne, Germany, bortle class 7.

These are my first results (cropped):
m81 and m82
57.5 mins (115*30 sec, iso 800) unguided, DeepSkyStacker, PixInsight
 

m27
71 mins (142*30 sec, iso 800) unguided, DeepSkyStacker, PixInsight


m31
87.5 mins (175*30 sec, iso 800) unguided, DeepSkyStacker, PixInsight


m51
50 mins (20 secs exposures, iso 800) unguided, DeepSkyStacker, pixinsight


Obviously I still have a lot to learn:D Suggestions and feedback are welcome! 

Cheers,

Pantelis

Thanks for the links and advice Wes. The DSLR-only setup is temporary as I’m looking at the 130PDS as that seems to be everyone’s go-to (pun intended 😊) as a good place to start for imaging.

I’ll look into getting a red dot finder where I can adapt it for the camera/scope in future I think as mounting it on the imaging unit be that to camera or a scope makes sense.

Thanks Harry for the Rigel recommendation. I’ll start there 😊

I have found the Rigel Quickfinder easy to install, adaptable, and affordable. I use it with a DSLR and seperatly  a 80mm  scope.

Ugh

For a camera only rig I guess I would find me a hot shoe adapter.  If we target a red dot with a synta mount then you could use this:


Then you could get a red dot such as this which would fit Into the bracket;


Now these two accessories add up.  But they would work. And the red dot would be useful in the future when you get a scope.  Not so much the hot shoe.

You can probably find a cheap red dot finder on cloudy nights classified.  Maybe a mount too.  But you can also mount a red dot with double sided tape or an elastic band if you can figure out where on your camera body.

The quality of the red dot almost does not matter.  Your problem really is how to attach it to your camera body.

The red dot need not be on the camera body but I don’t think you have any other place to put it that will stay aligned with the camera fov

It occurs to me one other thing about getting a 2-3 star with a camera lens.  You need to be careful to put that star in the dead center of the lens fov.  Difficult if low power and with no crosshair.  To the extent you don’t center the star your alignment will be affected negatively.
